WALTER B. NOYES, OF MANCHESTER, NEW HAMPSHIRE.

IMPROVEMENT IN SAW-GUMMERS.

Specification forming part of Letters Patent No. 152,675, dated June 30,1874; application filed June 20, 1874.

To all 101mm it may concern Be it known that I, WALTER B. NovEs, ofManchester, in the county Vof Hillsborough and State of New Hampshire,have invented certain new and useful Improvements in Saw- Gummers; and Ido hereby declare that the following` is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specification.

The nature of my invention consists in the construction and arrangementof a saw-gummer, as will be hereinafter fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the-same, I will now proceed to describe itsconstruct-ion and operation, referrin g to the annexed drawing, inwhich- Figure lis a longitudinal section of my sawgummer, and Fig. 2 isan inverted view `of the same.

A represents the gunnner, of semicircnlar shape, provided with a slot,a., in which the screws B B press against the sides of the saw. The slota does not extend entirely through the gummer, but leaves a suitableportion at each end solid. In these solid ends of the gummer are placedtwo rods, C C, which pass through the carriage D to guide the same. Ascrew, E, which has its bearings in the ends of the gummer, andprovided, at its rear end, with a knob or handwheel, G, is screwedthrough the carriage D, so that by turning said knob in either directionAthe carriage is moved either back or forth. In the lower end of thecarriage D is placed a shaft, H, provided, within the carriage, withelongated cogs b b, and at one end with a crank, I.

The operator stands on the back side of the saw, turning the crank Iwith one hand, and at the same time feeding up the cutter attached tothe carriage D by turning the knob Gr, the carriage being supported bythe rods c c. The object of this is to provide a means so that theoperator can see the direction the cutter is working, so as to cut on aline, and at the same time be able to remove and place the gummer on thesame cutting-line, so as to prevent the working irregular forms in theteeth.

I am aware that saw-gummers having movable carriages and set-screws forholding the sawV have been used, and therefore do not claim such adevice, broadly; but

HavingV thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The carriage D, constructed as described, and mounted upon the rods G C,in combination with the selnicircular slotted gummer A A and screw E,the several parts being ar` ranged as and for the purpose specified.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
